What happens if you don't wear swimming suit while swimming?

Answer 1

Swimming without swimming suit is not a good idea for anyone. Wearing a wet suit (non-swimming) for a long time can promote the growth of germs and bacteria which may cause allergy and itching in your body. But if you'll wear a proper swimming suit then you can reduce germs and bacterial growth upto a great extent. So its better to prefer a swimming costume instead of a simple suit.
